how to use the truncatesync function from the fs-extra library in typescript

To use the truncateSync function from the fs-extra library in TypeScript, you will first need to install the fs-extra package and add it to your dependencies using the following command:

index.ts
npm install fs-extra --save

2 lines

Once you have installed fs-extra, you can import the truncateSync function from the library like so:

index.ts
import * as fs from 'fs-extra';

const filePath: string = '/path/to/file';
const newSize: number = 1024; // new size of file in bytes

fs.truncateSync(filePath, newSize);

7 lines

In the code above, we import the fs-extra library and create a variable filePath which contains the path to the file we want to truncate. We also create a newSize variable which represents the new size of the file in bytes.

Finally, we use the truncateSync function from fs-extra to truncate the file to the specified newSize. The truncateSync function takes in two arguments: filePath and newSize. Since the function is a synchronous function, we do not need to use callbacks or promises to handle the result.
